Annual PPII Lateral Rehabilitation

Shorewood's 2011 Comprehensive Facility Plan included a goal to reduce inflow and infiltration (II) in the separated sewer areas of the Village by 40% by 2021. Lateral rehabilitation has been identified as a key strategy to achieve that goal.

A Private Property Lateral Rehabilitation Program (PDF) and Schedule were developed based upon the results of flow monitoring in Basins 1 and 6, both of which have been designated by MMSD as under-performing sewersheds. The schedule, illustrated at right, targets the block areas which have contributed higher-than-expected flows to the sanitary system during rainfall events during our evaluations.

The Private Property Lateral Rehabilitation Program is currently 100% funded through the MMSD and Village of Shorewood. Laterals are rehabilitated (lined) at no out-of-pocket cost to property owners identified in a specified program year.

Program Achievements to Date

257 private laterals, over 10,000 lineal feet of pipe, have been lined since 2012. View a list of property addresses.

2018 Program

The 2018 program includes wait list properties from the 2017 program (4000 to 4200 blocks of North Larkin Street). A contract is scheduled to be awarded by the Village Board at its June 18 meeting. Construction is anticipated to begin later this summer.

I am so pleased the Village of Shorewood is proactively addressing Infiltration/Inflow of storm water into the sanitary system. It was an easy decision to participate in the private property lateral lining program as I essentially got a “new sewer” to benefit both my property value and the Village's objectives of reducing I&I. I was very satisfied that there was very little disruption to my yard and the Village was timely in restoration of areas disturbed during the work.
